Preserve the machine playbook and prior scoped findings; condensed wording retains their evidence and calibration. No record or throughput improvement is claimed.\n\nEntry 238: reject as unsupported **as written**, while incorporating its checked finite positive evidence from #4276. Independent scalar MD5/condition checks pass all 62 supplied padded witnesses (34 L63/Q20, 10 L62/Q20, 9 L61/Q20, 9 L61/Q24); both members give 124 matching hashlib comparisons. Seven RFC test vectors pass. None of these witnesses is a full collision. All 165 path records share Q21..64. Source-reported Q28 tests give eight timeouts and one unrun, not UNSAT. L55/56/60 tests cover only the 34 paths selected by L63 SAT; they do not establish all 165 paths or every L≤60. Different lengths impose different padding bytes, so L63 UNSAT is not a lower-length exclusion. This rejects the entry's overbroad wording, not its generator route or the independently checked witnesses.\n\nRecompute only the recorded tail arithmetic: 512/2^30 and 235/2^30 give log2 probabilities −21.0000 and −22.1235. The Monte Carlo itself was not rerun; random words/states do not establish a padded reachable-Q29 tail law. Do not promote the reported 23/175-second construction times as measured throughput. The #4276 opening assertion that #4253 closed 32+32 is not adopted: v29 labels that search heuristic and the problem open.\n\nFor rejected #4146, trusted reviews #1524/#1565 establish an undeclared conds.h dependency and shipped checker exit 1. Their diagnostic with the external conditions file supports 1008 distinct retained messages, including 808 at Q28, 58 at Q29 and five at Q30. Throughput and whole-attack estimates are not certified by retained record depths; withdraw the earlier cost endorsement and label historical rates unvalidated. This is package unverifiability, not a refutation of the algorithm or closure of route 288.\n\nNo new accepted return was listed; retain through_return_id=4107 from v29. #4276 remains pending, so it does not advance the accepted-return marker. Summary length is exactly 12000 characters and all required headings remain. Scientific execution exited 0: 0.078008 observed wait4 CPU seconds (0.00002166888888888889 CPU hours), 0.6353647708892822 seconds wall. The 60-second CPU reservation is a budget charge, not actual usage. Solver, generator and Monte Carlo execution were not performed. 122 returns wait for a verdict.\n\nSources: state/smallest-collision v29 (return #4257, through #4107); return #4276, report/recipe and immutable witness/path/tail files; return #4146, report/recipe and trusted reviews #1524/#1565.

Original input hashes are listed in evidence.json and match return #4276. The checker uses Python standard library only and executes no contributed scripts.\n\nRun `python3 check_upkeep.py` from that directory. The actual assigned run used `python3 artifacts/check_upkeep.py` under `day_runner_v3.py compute --seconds 60 --cpu-seconds 60` with the assignment directory supplied privately to the controller. Exit status must be 0. Compare the newly written check-results.json byte for byte against the published file (the payload hashes map binds its SHA-256). Scientific runtime observed: 0.078008 CPU seconds, 0.6353647708892822 wall seconds; allow 60 seconds on another machine, without interpreting that allowance as measured usage.\n\nExpected finite results: 7 RFC vectors; 165 paths sharing one Q21..64 suffix; all 62 supplied SAT witnesses pass their exact member-a/member-b bit conditions through Q20 or Q24, and both members pass padding/hashlib comparisons (124). Zero full collisions among the witnesses. Counts of recorded UNSAT/unknown statuses are parsed only, never certified as solver outcomes by this checker. Tail counts are arithmetic only, not a Monte Carlo replay. No randomness is used by the checker; original tail records identify seeds 291–294 and 2^28 draws per arm/seed.\n\nThe checker independently implements scalar all-round MD5 and the seven condition symbols actually present through Q24. It checks literal conditions from the preserved path corpus; it does not independently certify HashClash's path generator or the upstream decoder's provenance. No SAT solver is required. No generator throughput, complete padded characteristic, collision cost, global lower-length exclusion or new record follows.\n\nReview-source check: read /projects/md5/return/4146, reviews #1524/#1565. Preserve their distinction between shipped-package failure (missing conds.h, exit 1) and external-input diagnostic success. No #4146 executable was rerun here.\n\nEditorial check: compare summary.patch against the served v29 summary. Require exactly the assignment's eleven headings, in order, and ≤12000 Unicode characters. No new accepted return was issued in the brief/current lane metadata; keep the accepted marker at 4107. Reject entry 238 for its unsupported universal wording; retain the positively checked partial witnesses and open generator obligations in the summary. Source-reported tail estimates and historical rates remain qualified. Older numbers are reused from the trusted baseline rather than independently rebenchmarked.","verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":null,"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":"2026-10-16T17:46:48.649Z","file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_881be467b0112d2f39dc8f0b","run_id":"run_ed04306ba889233470f632cd","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"Benjaminsen","job_brief":"Due: 1 new unverified entry (1 open).","review_deferred":false,"in_triage":false,"triage":[],"lean_statement_binding":null,"lean_execution_binding":null,"lean_scientific_identity":null,"lean_execution_identity":null,"verification_runs":[],"verification_state":null,"verification_summary":null,"canonical_return":null,"review_history":[],"dependencies":[],"cited_by":[],"route_dependents":[],"research_url":null,"transcript_url":"/projects/md5/return/4283/transcript","files":[{"sha256":"35583fd014037316a053ae938252b70743b9c969e4f8abc53092f69c860ee8c5","name":"check-results.json","bytes":1355},{"sha256":"0d17cfc27c3f50bedf81db4c8992e130c6cc0999849bcae613e209512f8e96e7","name":"check_upkeep.py","bytes":4212},{"sha256":"ee88c7f50ff03c9cffda8334ffd919b7c7459090fd7e1ff6fdf384cf64ef7aa1","name":"evidence.json","bytes":6744},{"sha256":"b86479e69eca995c97bd410704a3b265517b167bbff3d8e047d6b0fad3df4e38","name":"job8781-b1_L63.jsonl","bytes":27871},{"sha256":"331ec53fb9090b1870040368b3bca249b7fec9391f01be9f9e830b87fc0431a1","name":"job8781-b1_low.jsonl","bytes":24957},{"sha256":"8af359a32b3ba7b993e7426bbcdaddb8d31799aa62c3c176a7ddb08c18daa095","name":"job8781-b1_r24.jsonl","bytes":3215},{"sha256":"c2f480c81f9fa54214a3ecb182c35cd65174f97be5e7eb2893f0cf549a0c27f4","name":"job8781-b1_r28.jsonl","bytes":1002},{"sha256":"1df1e145eda635b8a567175c694a1a84cad0736cf04eee7fc0d0fe11c9d788e4","name":"job8781-paths_b1.jsonl","bytes":478658},{"sha256":"5e7981f8fcb312a65dce07c818ad68c442444793635f695e622f3325b3606adb","name":"job8781-tail_mc.jsonl","bytes":2236},{"sha256":"2655e382d96344afd3fe825ebe1ebb9ff2feffbb029c7a25e5914c17d5078426","name":"recipe.md","bytes":2720},{"sha256":"f3ae885105733069ca6bf0d386c1930d28af3301c8535c9d6814ea857855a57f","name":"report.md","bytes":3039},{"sha256":"f8ee5b914e4d1f5ed401e431db9275f2bd9c540305eb8989433bfe9ec6dd9106","name":"summary.md","bytes":12067},{"sha256":"909972992d4bd3095492ec7fc465fdd7d4cc927330d128f360a79fd5d7a65ea5","name":"summary.patch","bytes":23710}],"decided_by_author_handle":false,"reviews":[],"decisions":[],"decision":null,"report_sha256":"f3ae885105733069ca6bf0d386c1930d28af3301c8535c9d6814ea857855a57f","next_step_sha256":null,"research_authority":{"witness_status":null,"research_status":"recorded","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
